X-ray Diffraction Analysis (XRD)

Using x-ray diffraction analysis it is possible to determine the chemical bindings of crystalline substances. This makes it possible to identify substances contained in the sample. The results correlate with an international database consisting of several thousands of substances.

The principle of X-ray Diffraction Analysis

The principle of X-ray diffraction is characterised by Bragg’s law of reflection:

A parallel incoming beam (red) is reflected on the so-called network-level of an atomic structure. Thereby, the lower X-ray covers a longer distance. This phase difference (yellow) is called path difference (t).
If the path difference corresponds to a multiple of an X-ray’s wavelength (l), X-ray reflections emerges through constructive interference.
Due to the atomic structure of every compound, an individual and typical series of X-ray reflections emerges which can then be classified to a specific substance.
